How would the cap and trade bill be such a bad idea? The less you pollute, the less you have to pay. Giving companies an economical reason to reduce their pollution is, well, practically the only reason that a business would even bother to do it. If all we had in place for regulation where there are limits on how much you pollute, then it seems more then likely that companies would stay try and stay at that limit and make little to no effort to pollute less.
The reason I say that Greenland and polar bears would beg to differ, is because Greenland is actually starting to becoming green and polar bears are losing their habits.
